Outline of Final Research Achievements

Supramolecular organization between host and guest molecules utilizing the surface of metal nanomaterials is an interesting research topic in various fields such as optical,energy conversion, biological, and medical applications. Pentacene-alkanethiolate monolayer-protected gold nanoclusters (TP-Cn-X-MPC) and nanorods (TP-Cn-MPR) were successfully synthesized to examine the chain length (n =7, 11)-, structural size (X = S, L)- and surface shape- dependent structural and photophysical properties. The associate constants (Kapp) are largely dependent on the sizes of nanoclusters and alkyl chain lengths in TP-Cn-X-MPC (n =7, 11), whereas the Kapp values approximately remain constant in TP-Cn-MPR (n =7, 11). Efficient photocurrent generation was successfully observed on SnO2 films of pentacene and fullerene composites.
